Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To enable an astigmatic corrector and a focus corrector to be arranged at optimal positions by a method wherein correctors are so arranged at positions as to optimally correct the specific one out of aberrations. SOLUTION: It is preferable that focus correctors (focus coil) 50, 60, and 70 are arranged nearly at positions so as to minimize their currents, and required currents are lessened.

The same as above, the call 70 is preferably positioned near at a position P3, and a projection lens field becomes nearly maximum at this position. The coil 60 is preferably positioned slightly above a crossover point or near at a position P1. Therefore, focus coils are optimized, correction currents where the effects of currents are balanced are fed, whereby the curvature of an image plane can be dynamically corrected as a function of deflection.

Abstract: PURPOSE:To find the water permeability of the ground, etc., automatically in a short time by raising and lowering the pressure of injected water while holding the maximum flow rate of injected water to a water permeability test hole, and finding the relation between the pressure and flow rate of the injected water continuously. CONSTITUTION:The water in a water tank 1 is sent to a pressure container 5 by a pump 2 and a water level controller 7 holds the water level.

Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To suppress a rise in temperature of a motor and sufficiently provide a motor drive force by setting a control circuit in such a state as restricting the power, when the temperature of the motor reaches a prescribed temperature. SOLUTION: A torque signal is inputted in a control circuit 69 from a torque detection part 56, a drive signal is outputted from the control circuit 69 to a motor drive circuit 71 based on the torque signal so as to drive a motor 24 at the same torque, namely 1 to 1, and the motor 24 is controlled by switching of a switching element 70. Then, when it is used only in a low speed area such as an upslope, the motor 24 is driven at a prescribed property just after starting the drive, however, when the temperature is gradually risen and a signal from a temperature sensor 68 reaches a prescribed temperature, it is switched to a property of restricting the temperature from rising so that the output in the low speed area is suppressed. This constitution can suppress the rise in temperature of the motor 24 and sufficiently provide the motor drive force.

Abstract: PURPOSE: To reduce the effects of a spike by separating a 2nd capacitor from a resistor at the time of inputting a transient input pulse having short holding time and connecting 1st and 2nd capacitors to resistors at the time of inputting an input signal which has long holding time. CONSTITUTION: When voltage generated at the output terminal of an amplifier 1 based on a spike impressed to the positive polarity input terminal of the amplifier 1 is not a sufficient voltage for conducting a diode 15, a 2nd series circuit consisting of a capacitor 13 and a resistor 14 is separated from a 1st series circuit which consists of a capacitor 10 and a resistor 11 and a time constant is not unaffected. When an input is changed in a longer time, the diode 15 conducts, the resistor 14 is connected in parallel with the resistor 11, and the capacitor 10 is connected in parallel with the capacitor 13, so that the time constant of the circuit is changed. Consequently, a quick response to the normal change of input voltage can be generated, and the effect of the rise of a quick input voltage spike can be reduced.

Abstract: PURPOSE:To suppress deterioration in the quality of a coded image by dividing orthogonal transformation coefficients into a high frequency coefficient and a low frequency coefficient, quantizing respective coefficients and controlling quantizing levels. CONSTITUTION:A coefficient dividing part 10 divides transformation coefficients outputted from a DCT part 17 into a low frequency coefficient belonging to a low frequency area lower than boundary frequency and a high frequency coefficient in a high frequency area with a proper frequency specified from a coding control part 21 as a boundary.

The quantizing part 11 receives the lower frequency coefficient and outputs a quantizing coefficient together with a quantizing error. The quantizing part 12 simultaneously receives the high frequency coefficient and the quantizing error and outputs quantized results. The quantizing step size of the quantizing part 12 is smaller than that of the quantizing part 11. The quantizing step size is controlled by a coding control part 13.
